The team investigating the May 19 crash of an EgyptAir jet said it expects audio will be obtained from the plane's damaged cockpit voice recorder. Authorities hope the recordings will shed more light on what caused flight M804 to crash into the Mediterranean while en route from Paris to Cairo, killing all 66 people aboard.

The Airbus A320's flight data recorders indicate there was smoke in the plane's lavatory and on some of the onboard electronics. Authorities say heat damage and soot was found on the front part of wreckage of the plane.

The cockpit voice recorder was recovered in June and sent to Paris for repairs.

The Egyptian-led investigation team said Saturday the recorder's memory chips were not damaged.

Repairing some connecting components on the recorder's circuit board "enabled the reading of the recorders" the statement read.

No one has claimed responsibility for downing the plane.

On Monday French prosecutors opened a manslaughter probe into the crash, but stressed the inquiry was an accident investigation, not as a terrorism probe.
